Novak Djokovic retained his title at the World Tennis Championship exhibition tournament in Abu Dhabi on Saturday by rallying past Nicolas Almagro of Spain 6-7 (4), 6-3, 6-4 in the final.
The top-ranked Serb swept past David Ferrer in straight sets to reach the final, but he got a tough test from the 11th-ranked Almagro.
Almagro, a late replacement at the tournament for Rafael Nadal, rallied from 3-1 down in the tiebreaker to take the first set.
Djokovic broke to lead 3-1 in the second set on his way to evening the match. The third set was much tighter, with both players holding serve after eight games until Djokovic went up 5-4 and then broke Almagro to clinch the victory.
